No. Sonic, Knuckles, Tails, Amy, Silver, Blaze and quite a few other characters are friends with each other. Dr. Robotnik, Shadow, Rouge and Metal Sonic don't seem to have "friends", but they make alliances.

Not All the Characters but a Few...
You can find Sonic characters at Wikipedia and Google.

There is no youtube video about who Sonic characters marry in the future. I researched and found this web: http://archiesonic.wikia.com/wiki/Category:Mobians In this website you'll see ALL Sonic characters from the past, present, and future. You'll see who they marry and their children. I hope I answered your question.
